But the campaign’s main campaign angle has been to posit a Romney Economic Boom that would take hold on Romney’s election. So basically, all the formula and modeling doesn’t really matter because Romney’s policies would spur such massive growth that tax revenues just couldn’t help but go up and everyone would do great.

So a typical supply-side argument. But just look who the campaign is putting forward as the expert on the Romney Economic Boom.

I’m sort of surprised no one has pointed this out. It’s none other than Kevin Hassett.

Who’s Kevin Hassett?

Well, he’s none other than the coauthor of the spectacularly boomtime late 90s bestseller ‘Dow 36,000: The New Strategy for Profiting from the Coming Rise in the Stock Market’.

As TPM Reader WM points out, not only was the book amazingly wrong and basically assumed the tech boom was permanent, the whole concept was based on the idea that stocks should be valued on a “formula that double-counted earnings and dividends. A true classic in wingnut economics.”

Mitt Romney has had a tough couple of weeks on the campaign trail — and it shows in the latest Fox News poll. After a barrage of campaign ads, negative news coverage of his overseas trip and ongoing talk about his tax returns, Romney’s favorable rating and standing in the trial ballot have declined. As a result, President Obama has opened his biggest lead since Romney became the presumptive Republican nominee.

The president would take 49 PERCENT of the vote compared to Romney’s 40 PERCENT in a head-to-head matchup if the election were held today, the poll found.

Last month, Obama had a four percentage-point edge of 45 PERCENT to 41 PERCENT.
